"A person contravenes this section if he causes or knowingly permits any poisonous, noxious or polluting matter or any solid waste matter to enter any controlled waters."
"In my view, the crucial issue was whether Biffa was contractually obliged to act independently of STW and to provide tankering and perhaps other services whenever the situation demanded and without specific instruction from STW, or whether it its responsibility on3rd April 2003 was merely to provide such services and support, including tankering, as STW required of it during the day, both examples of shared responsibility and of Biffa working closely with STW, phrases used by Mr Rees in his interviews. In seeking to determine that issue I had to rely on the evidence of Miss Wetton and Mr Green, who alone gave evidence to the events on site on3rd April 2003 and the extracts and the interviews of Mr Rees upon which the prosecution principally relied."
"He [Mr Rees] made many general points about Biffa's relationship with STW, none of which makes clear precisely what Biffa's responsibility was on the day in question."
"My findings of fact in relation to what actually happened on site on3rd April 2003 are based on Miss Wetton's evidence and suggest that STW and not Biffa was managing the emergency incident, was in charge of the site, was the person responsible for ordering plant and services during that and the following day. STW asked for support and services when it required them and Biffa and others supplied them."
"Was I wrong on the evidence before me to acquit Biffa of both informations relating to3rd April 2003 because I was not satisfied to the criminal standard of proof that Biffa had any responsibility in the sewer on that day other than to provide such support and services, including tankering, as were required of it by STW which it did?"
